These rear trailing arm bushings are meant for your all-out track, autocross, or drift E30 monster; the bane of track times are any kinks your car may have in its proverbial chain. These solid Delrin E30 rear trailing arm bushings are one of those upgrades that give a definite edge. The Garagistic Delrin rear trailing arm bushings (RTABs) are a class of their own; if you've ever been in a car with Delrin bushings, you know what performance feels like. These RTAB's are designed with specific racing classes in mind, where your more solid or bearing-style bushings are not permitted. The last thing you want when you're tracking your bimmer is any type of unwarranted after-turn motions; with Delrin bushings, your suspension tends to react faster due to the stiffer durometer of these bushings. Since there is less wasted motion with a solid bushing, the suspension can react faster and give you more feedback.
The rear alignment of your E30, Z3, or 2002 stays where it's meant to during hard cornering, braking, acceleration, or any other strain it might experience. When you put your power down, it goes where it should; displacement of power is a major player in slower track times and general cornering; getting around those corners faster will make all the difference. The adjective you're looking for is planted. These BMW solid Delrin rear trailing arm bushings are a neat addition to your track monster, auto-X beast, or drift machine.

The stock rubber trailing arm bushings deflect and allow the rear semi-trailing arms to move in all kinds of unwanted directions causing an overall instability. As we mentioned above, this energy displacement slows your cornering and reduces confidence. Replacing your trailing arm bushings on your E12, 2002, E30, Z3, or E21 makes for much more fun putting your power where it needs to be. After all, what good is power if you cannot put it down? Stay the course with these bushings and learn the true difference they offer.
These solid rear trailing arm bushings maintain stock suspension geometry; These are much stiffer than the OEM units (75D) which will cause some NVH. Includes everything needed for installation. Bushings for all 4 connecting points on the trailing arms as well as steel sleeves. We touched on the benefits of BMW solid Delrin rear trailing arm bushings above. This is an upgrade you have to feel to believe; your bimmer and track times will thank you for it. True performance does not compromise.
Please keep in mind when shopping around for trailing arm bushings that a lot of competitors use aluminum for the race instead of steel. This is not a good idea. Nothing that rotates should be aluminum. It will wear. Its softer than steel. Your BMW OEM race was steel. So is ours. Another note regarding hardware and tolerances. We make our products compatible with our other parts as well as competitors. For example, these trailing arm bushings need to not only be compatible with our camber and toe kit (which requires BMW OEM eccentric Hardware) but with competitors as well. The bolt diameter on the eccentric hardware (OEM BMW) for those who make their rear subframe adjustable using our camber and toe kit (while they have the subframe out) is bigger than the old OEM E30 hardware (which could possibly be worn as well). So for this reason, we recommend that you replace your old, worn, tired and small stock hardware for bigger (and tighter fitting) hardware which you can find in the options list above. This is optional. However, it's a great way to get an even more precise feel in the trailing arms you can't get from other kits out there. Do it once, do it right. Kit includes 10.9-grade bolts, washers, and even nylon locking nuts. Everything needed for your install.
